Today we will discuss methods of receiving an electric shock and ways to avoid electrical hazards.

  • From defective extension cords.
  • From overloading a switch or over-riding a by-pass.
  • By not grounding electrical equipment.
  • By coming in close contact with live electric lines.
  • By coming too close to high power lines with the power arching over and making contact.
Ways to Avoid Electric Hazards
  • Always inspect tools and equipment for frayed cords and defective plugs before using them.
  • Never use a power tool that has had the ground plug removed; inspect the plug.
  • Never stand in water and operate a power tool without proper (i.e., insulated) footwear.
  • Keep extension cords out of water when in use.
  • Consider all power lines “live” and avoid contact with them.
